Description
Technical field
The present invention relates to a kind of overvoltage protector; It comprises support and at least one slipping into property protection member; This member comprises at least one nonlinear resistor elements and the device of separating nonlinear resistor elements from power main, and at least a portion is the device of the state of overvoltage protector to local and/or long-range transmission.
Background technology
Overvoltage protector includes protective element (protective element); This protective element is nonlinear resistor elements (rheostat) normally, and it little by little reduces its resistance owing to load to electric current and the applying of pulse on the shielded power main.As a result, the electric current that flows through slipping into property protection member (slide-in protective member) increases, and the temperature of slipping into property protection member rises.Therefore overvoltage protector also is equipped with heat sink.It is used under the situation that slipping into property protection member arrives special temperature slipping into property protection member is separated from power main, because slipping into property protection member is because its intensification no longer can proper function.(be signaled) is apprised of in the branch defection of slipping into property protection member and power main, promptly or directly on overvoltage protector, shows or utilizes the transmission of proper signal and inform.After slipping into property protection member was separated from power main, power main was just no longer protected, therefore, need come back to guard mode through the slipping into property protection member of changing overvoltage protector.
Overvoltage protector generally includes the U-shaped support that is installed in the supportive device, and it also is connected with the electric wire of protected circuit, to accomplish the simple replacement of protective element.Overvoltage protector also comprises slipping into property protection member, and it is equipped with contact, be arranged in the support and be connected to the circuit of protected power main with connection, and slipping into property protection member slips in the support.Therefore; Can easily replace in the slipping into property protection member; And be provided with the nonlinear resistor elements that is arranged on wherein and the thermal release device of nonlinear resistor elements; And, if desired, also be provided with the state that detects overvoltage protector is changed the remote signal of overvoltage protector with transmission appropriate device the device that the state of overvoltage protector sends with the visual signal form.
Known have many embodiment, yet their particular arrangement and employed parts all depend on the pulse current amplitude of energy load and process overvoltage protector circuit.The embodiment that uses at present also depends on employed manufacturing technology in the production in slipping into property protection member.The elementary object of the change of slipping into property protection member designs aspect is to keep the essential characteristic of overvoltage protector and reduce manufacturing cost simultaneously.
According to appearance patent DE29519313U1; Use the copper strips of setting as the well-known device of the tripper of linear resistor element; The one of which side is fixedly connected on the contact of slipping into property protection member, and is connected on the varistor electrodes through scolder suitable on the calorifics (thermally situablesolder) on the opposite side.Effect has a hinge bar (hinged level) on the setting copper strips, and the pressure of setting copper strips is provided through compression spring, and it is arranged on fixing between (motionless) shackle of hinge bar and the spring other end.Hinge bar not only is used for the vision signaling (visual signaling) of overvoltage protector state variation (rheostat is separated from power main), also is used for the information that acquisition is used for the state variation of long-range signaling (remote signaling).
The shortcoming of this solution is; Because the spatial configuration of slipping into property protection member; It does not allow in the sleeve of slipping into property protection member, to place the rheostat of (for example) parallel connected rheostat or large-size, and this has limited the changeability of the protectiveness characteristic of this solution when keeping the external dimensions that slips into protective element.Another shortcoming of this solution is to be used for the rheostat insulation and is fixed on the use of sealed mixture of the lining of slipping into property protection member, and this has increased cost.
According to file EP436881A1; Another known devices has been used resolution element; It is arranged perpendicular to rheostatic plane; And separating component is a copper strips, and the one of which side is connected on the contact of slipping into property protection member, and is connected on the output of varistor electrodes through scolder suitable on the calorifics on the opposite side.Resolution element is an arch, and its center is porose, and hinge bar stretches in this hole.The essential effect that hinge bar forms on resolution element through compression spring, and resolution element is moved to the position of guaranteeing that power main separates with rheostat at scolder after melting.
The shortcoming of this solution has been to use the resolution element of relative stiffness, the sizable active force of deformation requirements that its realize to separate, its make the parts that use in the system size quite greatly and so the cost of solution quite high.Another shortcoming of solution is the spatial configuration of this solution, and it has taken the inner space of slipping into property protection member body, and this space possibly be used for the rheostat of another rheostat or other size.
Another known devices as resolution element is used copper strips, and the one of which end is connected with varistor electrodes through suitable scolder on the calorifics, and the other end is connected with copper cash, and is connected on the contact of sliding component, and hinge bar stretches in the opening of resolution element.Hinge bar produces the power on the resolution element that acts on through compression spring.
The advantage of this solution is that copper cash is flexible parts, and its distortion only needs very little power, but the shortcoming of this solution is the increase of circuit upper-part quantity.This has increased the quantity of necessary tie point when making and has therefore increased the cost of making.
The objective of the invention is to remove or reduce at least these shortcomings of the prior art.

According to overvoltage protector operation of the present invention as follows.
If the overvoltage phenomenon takes place in protected circuit, overvoltage protector is carried out its function routinely, just is reduced to permissible numerical value to the overvoltage of protected circuit.Yet; Aging and the overload of (nonlinear resistor elements, varistor 8, one group of varistor etc.) because protective element; The performance of protectiveness member can change, and therefore electric current begin to flow through protectiveness member (varistor 8) and cause that protectiveness member (varistor 8) heats up.Come the heat energy of self-protective member (varistor 8) generally to be directed to output 9 and 11.The output of the bottom electrode 9 of varistor 8 little by little heats up thus.
Because the abundant intensification of the bottom electrode 9 of varistor 8, the scolder that connects this output and cable 10 begins fusing.As a result, this joint portion loses its rigidity and sliding component 4 is shifted to contact 5 to an end of cable through compression spring 45 beginning.The output of varistor 8 bottom electrodes 9 begins to separate with cable 10 like this, and therefore protectiveness member (varistor 8) separates with power main.In according to the embodiment shown in Fig. 1-3b, moving of sliding component 4 do not influence the position of bar 16 in initial phase.Yet the wall 4b of sliding component stops to be retained in the position of not drawing with barre 16, and passes through the skew next time of sliding component 4, and the wall 4c of sliding component 4 begins to act on the arm 16a of bar 16.Wall begins the hole 7c of the signaling arm 16b shielding vision signaling of bar 16 rotation and bar 16 on the barre stake 7b, through like this, has changed the vision signaling of overvoltage protector state.In the embodiment according to Fig. 4 a and Fig. 4 b, because bottom 16 mobile in (between the wall 4b of sliding component 4 and the 4c) crooked groove, the skew of sliding component 4 causes the rotation of bar 16; And the signaling arm 16b of bar 16 has shielded vision signaling hole 7c, obtains the vision signaling of overvoltage protector state variation thus.In the embodiment according to Fig. 5 a and Fig. 5 b, the skew of sliding component 4 is owing to the stepped wall 4d of sliding component 4 causes the rotation of bar 16, and the bottom 16a of bar 16 keeps and the contacting of stepped wall 4d through spring 16c.Therefore, the signaling arm 16b of bar 16 shielding vision signaling hole 7c, its vision signaling of arousing the overvoltage protector state changes.In all these examples, the projection that act as setting element 3 that moves through its compression spring that does not show of sliding component 4 is vacated the space, and setting element 3 projections, produces the long-range signaling of overvoltage protector state variation thus.Maintenance person is very easy to find in to the remote inspection of overvoltage protector or site inspection then, and special slipping into property protection member 2 needs to change.
The present invention be not restricted to this paper the embodiment that clearly describes or show; So long as according to principle of the present invention; Sliding component 4 that expert of this area and those of ordinary skill can be made, that utilize suspension acts on the low melting point joint portion of cable 10 and the electrode and the modification that vision signaling and long-range signaling combine of protected element (varistor 8), all is in protection scope of the present invention.
